In a transistor, the collector current is always · less then the emitter current because -

A

collector side is reverse biased and the emitter side is forward biased

B

a few electrons are lost in the base and only remaining ones reach the collector

C

collector being reverse biased, attracts less electrons

D

collector side is forward biased and emitter side is reverse biased.

Text Solution

Verified by Experts

The correct Answer is:
A
`I_(E )=I_(B)+I_(C ) therefore I_(C )lt I_(E )`.
A few electrons are lost to the base.
